If I start a new Python interactive session from the command line, some console features such as using the arrow keys to access a previous command, etc. are present.
If instead, however, I use code.interact()
to start an interactive session from inside a larger script, the escape sequences aren’t properly handled – e.g. pressing the ⮹ key prints ^[[A
instead of displaying the previous command. How do I enable this feature?

You can use readline
module to get arrow keys working
import code import readline import rlcompleter vars = globals() vars.update(locals()) readline.set_completer(rlcompleter.Completer(vars).complete) readline.parse_and_bind("tab: complete") code.InteractiveConsole(vars).interact()
